Krüppel-like factor 14, also known as basic transcription element-binding protein 5 (BTEB5) is a protein that in humans is encoded by the KLF14 gene. The corresponding Klf14 mouse gene is known as Sp6. [1 ] [2 ]
Function [ edit ]
KLF14 is a member of the
Krüppel-like factor family of transcription factors. It regulates the transcription of various genes, including TGFβRII (the type II receptor for TGFβ). KLF14 is expressed in many tissues, [3 ] lacks [4 ] introns, and is subject to parent-specific expression. [5 ]
KLF14 appears to be a
master regulator of gene expression in adipose tissue. [6 ]
Protein structure [ edit ]
Like the other members of the KLF family, KLF14 has three
zinc-finger domains near the C-terminus, all three of which are of the classical C 2H 2 type. In the human, they are at amino acids 195–219, 225–249, and 255–277. [7 ]
Human KLF14 is 323 amino acids in length, with a molecular weight of 33,124;
in the mouse its length is 325. [7 ] [8 ]
Clinical significance [ edit ]
There appears to be a connection between KLF14 and
coronary artery disease, hypercholesterolemia and type 2 diabetes. [9 ] [10 ]
